M.H.
Try Goo Gone Sticker Lifter, and follow that with a lot of scrubbing and scalding hot soapy water. There's also Goof Off 2, which is water based. If anything is left after that, you can use rubbing alcohol and try lifting the last of it up with Duct Tape (stickum to lift off the stickum!) I once accidentally washed a blouse that had a big round election sticker on it. There's also something called Basic-H and KrudKutter but I've never used them.
